It was attributed to the formation of a boundary lubricant film well-bonded on the rubbing steel surface by way of adsorption and tribochemical reaction under heavy load,owing to the polar-group of molecular adsorbed onto the metal surface,and the hydrophobic long chain alkyl formed the absorbed film.

这可能是由于N-油酰基谷氨酸三乙醇胺盐中的极性基团吸附在钢球表面、长碳链疏水性烃基在金属表面形成较厚的保护膜、在较高载荷条件下发生化学反应并形成高强度摩擦化学反应膜的缘故。

There were significant differences in plant height, grain number per spike and kilogram weight between the expreimental materials. The leaf length, leaf width, plant height and stem diameter of six-row barley were significantly more than those of two-row barley.

变异分析表明,供试材料间在株高、穗粒数、千粒重上存在极显著的遗传差异。Z检验法显示,六棱大麦的叶长、叶宽、株高和茎秆直径都极显著地大于二棱大麦。

Encapsulant was driven by capillary force into the space between the chip and substrate. Underfill technique can protect the electrical device and prevent the device from destroying because of external force. Underfill has many defects including the fill time is too long, the situation of short shot and air trap are caused easily, the yield of product of Flip-Chip is not highest and the products are universal. Therefore, there are many factors being studied in this paper to sum up the influence of underfill of Flip-Chip process cause by model parameters.

覆晶接合技术为先进电子讯号连接技术中的一种,具有高I/O数、电子讯号路径短以及尺寸小等优点,而采用覆晶接合之电子元件大部分均以底部充填技术进行封装;底部充填是一种以毛细作用为驱动力在晶片与基板之间的间隙充填底胶的封装技术,可以确保晶片不受到外力的影响而损及封装体,但此技术具有充填时间长、容易产生短射与包风等缺点,使得覆晶封装制程良率不高,间接影响覆晶封装产品的普及率,因此本文将依各种可能之参数模型对覆晶封装底部充填制程的影响,以供业界参考。

More than 10 QTL were detected in heading date, plant height, tassel branch number, tassel length, ear height and stem diameter, respectively.

This kind of gratings can be kept in the material for a long time. A mode of molecular reorientation was used to explain the formation mechanism of these gratings and it is well consistent with our experimental results. 3. Three kinds of azobenzene polymers P , P (MMA-co-GY7) and P (MMA-co-GO13) were synthesized by radical polymerization. High-density optical storage and the three-dimension (3D) microstructures in the azobenzene polymer films were presented. Twenty gratings have been stored on the same spot in our material. It is twice as many as the best recording that has been reported. It is the first time, a rectangular microstructure and a complicated double layers nesting six-pointed star microstructure are inscribed in it by using a simple two-wave couple setup.

采用共聚反应设计合成了单偶氮苯聚合物P、双偶氮苯聚合物P(MMA-co-GY7)和P(MMA-co-GO13)三种聚合物,研究了偶氮苯聚合物薄膜中的高密度光学存储和3维微结构,成功的将20套光栅储存在样品中同一个点上,是已有报道的两倍;并首次用简单的2波混频光路在该材料中刻写出长方格子和六角星型的微结构,在制作多重不同周期不同角度的高密度光栅结构实验过程中,发现不同周期光栅的刻写顺序对整个微结构形成的最终结果具有决定性的影响,并用相衬显微镜观察了这些微结构图像。

For sample with longer GI time, which resulting in the better uniformity of this sample, the unusual decrease of FWHM is not observed in the measurement of the temperature dependent PL spectra. Considering the better uniformity of the sample, the effect of carrier redistribution on PL spectra is unapparent. Therefore, the FWHM increases gradually with temperature.

对於成长中断时间较长的样品来讲,由於其均匀度较佳,所以在变温的光激光谱量测中,我们并未发现半高宽随温度上升而有下降的趋势,这是因为载子重新分布效应对一个均匀度佳的样品来讲,其显示出来的效果并不明显,所以我们只能观察到电子与声子散射效应所表现出来的现象,也就是半高宽随温度上升而缓慢增加。
